APPARATUS FOR CUTTING AND HANDLING CAN-END LINERS.

Original application filed July 18, 1916, Serial No.'109,943.

Divided and this application filed August 558, 1920.

T 0 all 10 tom it may concern- Be it known that I, Crrannns Giuiinir, a citizen of the United States, residing at Allendale, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in lipparatus for (hitting and lilandlinp; (,andind Liners, of which the following is a specificatii'in.

The invention relates to cutting and handling can end liners in bulk, previous to applying them to can ends; and. handling gasket material in the shape of core discs, cut from the centers of the liners, and in the parts and combinations thereof hereinafter set forth and claimed.

With such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanyingdrawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration. In the said drawings Fig. l is a front elevation of the machine arranged for automatically feeding disc blanks from an inverted core stack for cutting smaller cores and ring liners and as sembling them into stack formation, the same as when out from a strip or web.

Fig. 2 is a side elevation of Fig. 1.

I have referred particularly to cutting liners from paper or like material. Paper or such fibrous material is, however, only Patent No. 1,355,640, dated October 5, 1920.

taken on line XXVII JXVIII Fig. 6,

one of the many materials suitable for gaskets or liners for can ends. Rubber compositions have been used for many years. Such material as cellulose compounds, rendered somewhat flexible and yielding by admixture with softenin a en'ts. such for b 23 instance as acetic acid compounds of cellulose, similar to cellulose acetate in colloidal form. which may be produced by partial acetilization of the original cellulose material; also compositions of gelatinc or other albuminous matter rendered pliable by a suitable softening agent such as glycerine, are entirely suitable for the purpose, as long as theywill fold into the double seam without cracking or checking. Thin sheet metal of a soft and yielding nature, such for example as tin foil, is also suitable for liningcan ends.

it is possible to impregnate cloth with suitable surfacing material so as to render it available for gaskets. I, therefore, wish to extend my means for handling can end liners, to the use of any material from which can end. liners can be made. i

Referring to the drawings, the machine illustrated is adapted for cutting ring, liners from disc blanks previously cut from a web or strip. These disc blanks may be produced by any suitable cutting mechanism,

. placed in the machine herein illustrated, as

shown in Figs. 1 to The mechanism for feeding individual discs from the inverted delivering stacks consists of an intermittently rotatable feed disc or plate 30, mounted to rotate in a rocking feed ring 31; this feed ring is operated through the link 32, and pivoted lever 33, pivoted at 3- The lever 33 is operated from a link 35 and crank 36, the crank 36 being secured to the ver-* tical drive shaft 37 and having continuous rotation. A pivoted lever 38 operated by a cam 39 on the shaft 37, serves to operate a locking and aligning dog 10, which looks the feed disc 30against rotation and aligns the disc blanks fed thereby with the cutting punch 6.

The-feed disc 30 is of thin sheet metal of practically the thickness of the disc blanks 15 and the inverted stack holder 12 rests directly on the feed disc 30. The feed disc 30 has preferably four orifices 30 41-) of a diameter to just admit a disc blank at each step movement of the disc 30; the disc blank resting in the orifice directly under the stack of blanks, is stripped from the bottom of the stack and transported into alignment-with the cutting punch 6, that is, from positiona Fig. 3 to position I); the disc blank at'b is perforated by the punch 6 and the core center pushed down through the die 8 into the underneath receiving stack carrier 12, the ring liner 15 remaining in the orifice 30 of the feed plate 30; at the next step movement of the feed plate 30 another disc blank is transported from position a to position b and the previously cut liner 15 in the orifice 30 at position 7) is transported to position a, where it is pushed through the orifice die. opening 9 onto the stack core 11, where a stack of ring liners is accumulated as the machine operates. A weight 11 (Fig. 2) serves to cause the liners to feed along the core 11, as liners are removed successively by the can end lining machine through theoperation of the feed mechanism. Sucha machine is set forth in my companion application Ser. No. 106,672, filed Aug. 28, 1920. The said weight does not have afeeding, function in the machine herein claimed but inthis machine is arranged and prepared relative to the ring liners for its feeding function in the llrnng machine. It is necessary to operate the feed disc 30 with some precision as the orifice 30 must align simultaneously at position, a, I) and c. The mechanism for accomplishing this precision movement is operated from the vertical shaft 37, the continuous rotation of this shaft carrying the crank 36, oscillates the link 35, the lever 33, and link 32, thereby giving a rocking motion to the feed ring 31.

The feed ring 31 carries a pawl 31 (Fig. that engages into recesses 30 around the edge of the feed plate 30. The edge of the feed plate 30 is reinforced with a ring 30 5 and 6). During the rotary movement of the ring 30 the locking dog 40 is drawn out of engagement with the disc 30, through the action of the cam 39 rotating with the shaft 37, and as soon as the feed plate 30 reaches an end of its step movement the dog 10 is instantly moved by the cam 39 and lever 30, into engagement with the ring 30 secured to the disc 30, entering a wedge shaped opening 10 (Fig. 5) therein, thus locking and aligning the feed plate 30 with the stations (I, b and 0.

The inner end of the locking dog 40 is reduced in thickness and passes under the feed ring 31 (Fig. 6) and enters the wedge opening -10 inthe lower side of the reinforcing ring 30 When operating on core discs the cutting punch '7 does no cutting but acts simply as a stripping punch, pushing the ring liner from the orifice 30 onto the stack carrier 11..

The manner of placing the stack unit into a lining machine and applying the liners to a can end, and means for such purpose, are set forth in my companion divisional application Serial No.- 406,672, filed Aug. 28, 1920. p

This application is a division of my application Serial No. 109,943, filed July 18, 1916, now Patent No. 1,355,040.

It will be understood that the described mechanism may be supported and operated in any suitable or known manner. I have shown for the purpose a base frame or housing 1 having bolted thereto upright frame members 2 and 3 having suitable bearings for the support of a main driving shaft 4: provided with a pulley 4. This shaft is geared, as seen in Fig. 1, with the said vertical shaft 37 to rotate the same continuously. The shaft 4: is provided. with a cam or eccentric of usual construction which reciprocates vertically a cross head 5 guided by said frame members 2 and. 3, and the cross head carries the punching and depositing members 6 and 7 already referred to. 7 is a yielding pilot member adapted to enthe upper end of the ring liner stack holder 11 at the time when the .cut ringsliner is being deposited thereonby the annular die or pusher 7.

The liner stack holder 11 and the core stack holder 12' aresupportedby a'vertically movable cross head 10 (Fig. 1) on which is a tilting holder 10 for the liner stack holder, and after said stack holders have beenplaced on thecross head thelatter is liftediby means of the handle 10, as more fully explained in my said other application.

10 is a supporting post held on the tilting holder or socket l0 and extending up Within the liner stack holder to center the upper end of the same.
